I saw that same box at Flatwoods Outfitters in Hubert, NC this morning and they were asking a pretty penny for it.
Empty.
The box isn't in the best shape (top is torn as you can see) but the ammo is pristine. Thats a great store BTW
...actually found 16ga buckshot at Flatwoods, but I wasn't gonna pay their prices
I think it's easier to find ammo for a Cheasapeake Punt Gun.
